Selecting Bits
When selecting a bit, use the right type for
your job. For best performance, always use
sharp bits.
Drilling
1. Before drilling, be sure the workpiece is
clamped securely. Use backing material
to prevent damage to the workpiece
during breakthrough.
2. When starting a hole, place the drill bit on
the work surface and apply fi rm pressure.
Begin drilling at a slow speed, gradually
increasing the speed as you drill.
3. Always apply pressure in line with the bit.
Use enough pressure to keep the drill
biting, but do not push hard enough to
stall the motor.
4. Reduce pressure and ease the bit
through the last part of the hole. While
the tool is still running, pull the bit out of
the hole to prevent jamming.
Drilling in Wood, Composition Materials
and Plastic
When drilling in wood, composition materials
and plastic, start the drill slowly, gradually
increasing speed as you drill. When drilling
into wood, use wood augers or twist drill bits.
Always use sharp bits. When using twist drill
bits, pull the bit out of the hole frequently to
clear chips from the bit fl utes. To reduce the
chance of splintering, back work with a piece
of scrap wood. Select low speeds for plastics
with a low melting point.
APPLICATIONS
1. Clean and lubricate the threads on the
adapter and core bit as indicated (Fig. 5)
to make later removal easier. Screw the
threaded end of the adapter into the rear
of the core bit.
2. Push the guide plate onto the pointed
end of the center pin. Insert the center
pin with guide plate a ssembly into to the
core bit. Be sure the small end of the
center pin is securely placed into the
hole in the center of the adapter.
3. Insert the adapter into the bit holder of
the tool as described in “Inserting Drill
Bit or Chisel”. Set the rotary hammer/drill
lever to rotary hammer.
4. Press the center pin fi rmly against your
center mark, hold the tool fi rmly and pull
the trigger.
5. After drilling to about the depth of the
core bit teeth, remove the center pin and
guide plate from the core bit. Resume
drilling.
6. After you have fi nished drilling the hole,
hold the tool upwards, pointing it away
from your body, and run it briefly in
forward to loosen the core bit from the
adapter.
MILWAUKEE Heavy-Duty Thin Wall Core
Bits drill holes up to 3" deep. To make deeper
holes, remove the bit, break and remove the
core. Resume drilling.
Cleaning
Clean dust and debris from charger and tool
vents. Keep tool handles clean, dry and free
of oil or grease. Use only mild soap and a
damp cloth to clean the tool, battery pack
and charger since certain cleaning agents
and solvents are harmful to plastics and other
insulated parts. Some of these include gaso-
line, turpentine, lacquer thinner, paint thinner,
chlorinated cleaning solvents, ammonia and
household detergents containing ammonia.
Never use fl ammable or combustible sol-
vents around tools.
WARNING
To reduce the risk of injury,
always unplug the charger and
remove the battery pack from

tool, battery pack and charger to a
MILWAUKEE service facility for:
• Lubrication
• Mechanical inspection and cleaning
(gears, spindles, bearings, housing,
etc.)
• Electrical inspection (battery pack,
charger, motor)
• Testing to assure proper mechanical and
electrical operation
Maintaining Tool
If the tool does not start or operate at full pow-
er with a fully charged battery pack, clean
the contacts on the battery pack. If the tool
still does not work properly, return the tool,
charger and battery pack, to a MILWAUKEE
service facility for repairs.
